Ranking the influence of key uncertainties in the curing of thermoset laminates

Résumé

The different characteristics of high and low thickness laminates means it is often optimal to process them under different conditions. Processing parts with tapered thicknesses can therefore be an issue as the entirety of the part must be processed in the same environment. To better understand how a processing environment can be optimised to minimise inhomogeneity across a tapered part, sensitivity analyses and Monte-Carlo simulations were performed. The sensitivity analyses showed how changes in key processing parameters affect the sensitivity of cure time to part thickness under different conditions. The results gave strong evidence to suggest that environments with a high heat transfer coefficient and a cure cycle designed for thick laminates were the most conducive to producing tapered parts with the greatest spatial uniformity. Results from the Monte-Carlo simulations showed the cure cycle recommended for thick Hexply M21 laminates was suited to most tapered parts but was highly conservative.
